E.P.A.S

• EPAS


  Electronic product assembly and servicing
• Electronic product assembly and servicing


  • Manufacturing and maintaining electronic devices
  • Detection and repair of assembly defects in electronic units
• Electronics


  • The study of how to control the flow of electrons
  • Deals with circuits made with components and connecting wires that control the flow of electricity and direct it to do useful things and convert them into electric current and voltage signals

  
• Electronic components


  • Resistor
  • Capacitor
  • Integrated Circuit (IC)
  • Diode
  • Transistor
• Semiconductor


  A material like silicon that can conduct electricity much better than an insulator but not as well as metals
• Diode


  Allows an electric current to pass in one direction while blocking current in the opposite direction

  
• Transistor


  A semiconductor that can amplify and switch electrical power and electronic signals
• Types of wires/cables used in electronics

  • Shielded Twisted-Pair Cable
  • Unshielded Twisted-Pair Cable
  • Phone and Data Wire
  • Coaxial Cable
  • THHN/THWN Wire

  
• Shielded Twisted-Pair Cable


  Encases the signal-carrying wires in a conducting shield to reduce electromagnetic interference

  
• Unshielded Twisted-Pair Cable


  Relies on balancing and filtering techniques using media filters instead of physical shielding to block interference
• Coaxial Cable

  A round jacketed cable with an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield made of braided wire

  
• THHN/THWN Wire


  Single conductors with color-coded insulation, protected by tubular metal or plastic conduit instead of a plastic sheathing

  
• Common faults in resistors are open and producing noise
• Common faults in capacitors include expansion of the shell, oil leakage, abnormal internal sound, and temperature rise of the shell higher than 55 degrees Celsius
• Factors to consider when choosing the right material for components and assemblies

  • Selection of Material
  • Testing of Material
  • Cost of Material
• Selection of Materials


  • Copper, nickel, chromium, aluminum, lead, silver, and tin are often used for their conductivity and malleability
  • The main goal is to minimize cost while meeting product performance goals
• Testing of Materials


  • Determination of the technological and operational properties of materials, primarily using machines and instruments
  • To determine properties of raw materials, check quality at intermediate stages, check finished products, and aid research
• Cost of Materials


  The cost of materials used to manufacture a product or provide a service
• Steps to assess quality of received materials

  • Match the packing slip to the items received and ensure the materials are destined for your department
  • Ensure you are receiving materials indicated on the purchase order regarding quantity and discount
  • Ensure the materials are in acceptable condition
  • Ensure terms regarding installation and/or set up of equipment are met
• Receiving Reports


  • The person receiving the goods must document, using the administrative software, that all goods were received for each requisition before any payment can be made to the vendor
  • Any exceptions must be noted so that partial payments can be processed, or defective goods can be returned
• Return of Merchandise


  When merchandise is received that is incomplete or defective, the supervisor will return the materials to the supplier or to the store where it was bought and decide with the vendor for replacement
• Quality Standards


  Documents that provide requirements, specifications, guidelines, or characteristics that can be used consistently to ensure that materials, products, processes, and services are fit for their purpose
• Why do we use quality standards?

  • Satisfying their customers' quality requirements
  • Ensuring their products and services are safe
  • Complying with regulations
  • Meeting environmental objectives
• Standard Operating Procedures (SOP)


  Written, step-by-step instructions that describe how to perform a routine activity
• Why do you need SOP?

  • It will give you a better understanding of your business processes and move forward
  • It ensures that all employees are performing the business processes in the same way
  • It gives you the option to scale your business more quickly
• Occupational Health and Safety (OHS) Standards

  Standards related to health, safety, and welfare issues in the workplace, aimed at making the workplace better for workers, co-workers, family members, customers, and other stakeholders
• Hazards


  Something that can cause harm or anything that could hurt you or someone else
• Types of Hazards


  • Physical Hazards
  • Biological Hazards
  • Ergonomic Hazards
  • Chemical Hazards
• Types of Work-Related Errors

  • Quantity of work (untimely completion, limited production)
  • Quality of work (failure to meet quality standards)
• Quantity of work (untimely completion, limited production)


  • Poor prioritizing, timing, scheduling
  • Lost time (tardiness, absenteeism, leaving without permission, excessive visiting, phone use, break time, use of the Internet, misuse of sick leave)
  • Slow response to work requests, and untimely completion of assignments
• Quality of work (failure to meet quality standards)


  • Inaccuracies, errors
  • Failure to meet expectations for product quality, cost or service
  • Customer/client dissatisfaction
  • Spoilage and/or waste of materials
  • Inappropriate or poor work methods
